openinverter forum

Hi, folks.
(I still cannot believe that I am writing this, but…) I am posting my VW 1972 camper van converted to EV for SALE.
Located in the SF Bay Area. Available for in-person viewing starting May 7. PLEASE DM ME.

This is a DIY conversion. Drivetrain and core systems run perfectly; some secondary features are WIP (see below). The camper has a custom interior setup and is ready for your camping trip. I’ve driven it around the SF Bay Area and to Yosemite (Valley Village EV chargers – looks awesome next to modern EVs with the granite backdrop).
I'm currently away. But I can post more pictures of the build, documentation and the firmware. I can also provide initial support to the buyer to set you up for success.

I’m hoping to recover major parts cost. Honestly, I really don’t want to sell it, so please no lowball offers.

Components:

• 1x Camper van (California registration) - $12,000

• 14x Tesla modules 5.3kWh with original BMS boards - $12,000

• 1x SIMP BMS

• 1x Tesla MS RSDU - $1,100 (+ spare inverter + spare OI board)

• 2x Battery box aluminium enclosures ~ $1,000

• A set of 4x new tires - Hankook Vantra LT RA18 195 - $750 (brand new 04/2025)

• 1x Elcon\TC Charger (6.5kW) + DCDC (1.5kW) converter combo ~ $1,000

• 1x iBooster from Tesla MX

• 1x Fisker Ocean Battery heater

• 3x Tesla MS coolant pumps

• 2x Tesla MY radiators

• i3 BMW LIM for AC/DC CCS1/US charging

• i3 BMW AC/DC CCS1/US charging socket

• Bespoke VCU (will provide firmware)

• Bespoke dashboard controller with Nexus gauge (will provide firmware)

Some details:
Cooling loop 1 (power electronics, done)
Reservoir (out) -> pump (PWM via VCU) -> radiator -> Inverter (CAN bus + IO) -> OBC/DCDC (CAN bus + IO) -> motor -> reservoir (in)

Cooling loop 2 (batteries) (WIP, not filled with coolant).
*I didn't see any issue driving and AC charging without this loop

• 2x battery packs with coolant hoses complete and outlets

• 2x Tesla coolant pumps (perhaps 1x is enough, but you'll have 2x)

• 1x radiator (temp mounted - easy to remove if needed)

• Battery heater

DC Charging is setup and working. I know it works, because I used CCS chargers on the road to charge the camper van when AC chargers were unavailable. I simply used BMS charging menu to set the charging current limit to max 25A which LIM then communicates to the charging station.
